COMBINED SAFETY AND BOLT LOCK FOR GUNS.

Specification of Letters Patent;

Patented Oct. 14, 1919.

Application filed February 14, 1919. Serial No. 276,944.

To all whom it may concern Be it known that I, FRANK A. W ILLIAMS, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Combined Safety and Bolt Locks for Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to guns of the bolt action type and has particular reference to constructions in which the rear sight is mounted above the bolt. It is the primary object of the invention to obtain a construction of safety which does not interfere with the sight mounting. And further to obtain a construction which performs auxiliary functions as hereinafter set forth,

In the drawings:

Figure 1 is a side elevation of a bolt ac tion gun, showing the rear sight mounted above the bolt and provided with my improved safety;

Fig. 2 isa rear elevation of the bolt and h Fig. 3 is a similar view of the sight detached;

Fig. 4 is a plan View of the sight;

Fig. 5 is a longitudinal section thereof;

Fig. 6 is a cross-section;

Fig. 7 is a longitudinal section throughthe sight, sleeve, firing sembly detached;

Fig. 8 is a cross-section thereof in the central plane of the safety;

Fig. 9 is a horizontal section; Fig. 10 is a plan View showing the relation of the safety and bolt lock;

. Fig. 11 is an end elevation of the bolt locki F ig. 12 is a cross-section through the bolt in the plane of the look.

A is the gun stock, B the frame, C th bolt, D the actuating bolt handle, E the pin and safety as sleeve, and F the firing pin of a standard bolt action assembly. G is a rear sight assembly which is mounted upon the, sleeve E, but which is also provided with a bearing portion H for slidably engaging the frame so as to accurately position the sight. The construction of'the sight assembly forms no part of the present invention, but as shown comprises a leaf frame I which is pivotally and laterally adjustably mounted on the shaft J in the bifurcated bracket member K, while a vertically adjustable spring frame L engages the leaf and carries the peep sight M.

The mounting of this sight above the sleeve interferes with the use of a rockable safety such as are provided on standard bolt actions, and I have therefore devised a safety of the following construction: N is a bar which slidably engages a transverse aperture in the sleeve between the mount ing for the sight and the firing pin. Upon the lower face of this bar are the projecting ribs or teeth 0 adapted to en rage corresponding ribs or teeth P on the firing pin. The bar N is of greater length than the bearing in the sleeve so that it can be adusted in position by pressure on the proecting end into any one of three different positions. The lower surface of the safety Is also cut away at Q so as to permit, in one position of its adjustment, the free movement of the firing pin, while in the other positions of adjustment the engagement of the teeth 0 and P will lock said firing pin. The entering ends of the teeth 0 are slightly beveled at 0 so that in engaging with the teeth P the pin F'is slightly retracted. This has the effect of withdrawing the cooking nose B, so that incase the sear is withdrawn it can return again into position for engagement with the firing pin.

The safety N is held in its several positions of adjustment by a spring pressed detent S which is arranged in a longitudinal bore in the upper portion of the sleeve E.

This detent S also performs the function of a bolt lock and to this end comprises a hollow member S and a pointed nose member S at one end thereof. S is a cross pin engaging an elongated slot S in the member S, and S is a spring within the hollow member interposed between the pin S and the nose piece S The safety N is formed with a notch T for engaging the nose piece S when in one position of adjustment, in which position the opposite end of the member S" is projected beyond the'bore and into engagement with a recess U in the bolt so as to lock the boltfrom turning. The safety N is further provided with a groove T into which the nose piece S is forced by the tension of the spring S when said safety is in the second or third position of adjustment. In either of these latter two positions the member s is retracted into the bore and is thereby withdrawn from en T will hold the member N with the teeth 0 in full engagement with the teeth P, and

. therefore the firing pin is locked from movement within the sleeve. At the same time the member S being projected into engagement with the notch U prevents the rotation of the bolt. If it is desired to release the bolt and at the sametime to continue the locking of the firing pin, the member N is adjusted to its intermediate position, where the nose piece S is in engagement with the slot T The teeth 0 and Pare still in engagement with each other so that the firing pin is locked, but the movement of the nose piece S into the slot T 2 permits the spring to withdraw the projecting end of the member S, disengaging the same from the notch U and freeing the bolt for rotation. Thus, the operator is permitted to remove the bolt while the firing pin remains locked. In the third position of adjustment the cut away portion Q, of the member N registers with the firing pin, so that the latter is free to move whenever released by the sear and the gun is consequently in condition for firing.

A safety constructed as above described in no way interferes with the sight assembly, for the member N is below the bifurcated member K in which is mounted the transverse pin J carrying the sight leaf. Fur thermore, the safety may be manipulated more easily and conveniently than the rockable construction which has heretofore been used.

What I claim as my invention is:

1. In a gun of the bolt action type, the combination with a sleeve for the bolt having an upward extension forming a mounting for the sight, of. a safety transversely adjustably mounted in said upward eXtension and engageable with the firing pin.

2. In a gun of the bolt action type, the combination with a sleeve for the bolt having an upward extension forming a mounting for the sight, of a safety in the form of a transversely slidable bar engaging an aperture in said upward extension between the sight mounting and the firing pin and engageable with the latter to lock the same.

3. In a gun of the bolt action type, the combination with a sleeve for the bolt having an upward extension forming a mounting for a sight, of a safety in'the form of a transversely slidablebar having a tooth on the lower face thereof for engagement with the firing pin and being cut away at one point to clear said pin.

a. In a gun of the bolt action type, the combination with a sleeve for the bolt having an upward extension forming a mounting for a sight, of a safety in the form of a transversely adjustable bar engaging an aperture in said sight mounting and projecting beyond the same, said safety being adjustable into a plurality of positions and having a tooth fOr engagement with the firing pin in one of said positions and cut away to clear said firing pin in another position.

5. In a gun of the bolt action type, the combination with a sleeve and the firing pin therein, of a safety in the form of a transversely movable bar mounted in said sleeve, said safety bar having a tooth thereon for engaging said firing pin when in one position of adjustment and being cut away to clear said firing pin in another position of adjustment.
